Abstract: A sample of seven behavioral traits of lateral functional dominance (e.g., hand clasping, handedness, arm folding, leg folding, foot preference, stride type and eye preference) was examined on 507 high school students (269 males, 238 females) of the Han ethnic group of Hunan. The results of this research are as follows. The percentage of the right side of five traits are much higher than that of the left side, except for arm folding and stride type. There is no sexual difference in the hakka of four traits except in handedness, arm folding and foot preference. From published materials, the percentage of R-R type of hand clasping, stride type and the percentage of R-R type of handedness are at the middle level; the percentage of R-R type of arm folding and leg folding are at the lowest level; whereas the percentage of R-R type of foot and eye preference are at the highest level. Factor score analysis showed variation between ethnicities of the Han nationality but also similarities with the northern groups of China. These differences in behavioral traits of lateral functional dominances in the China nationality are mainly ?reflected? in? folding ?arm? rate ?difference,? and? preferential? foot? rate? difference.
